Does the crankshaft have to be removed to install these seals?They seam similar to the Jeep 258 and 242 rear mains. They can be installed by simply pulling the rear bearing cap and pushing the old seal out pushing the new in. Install lower have seal in bearing cap.

Willys Jeep Parts Tech:
You can do it without. I think we may have a video or pictures showing how too.

Is the US made seal better than the other neoprene seal (800093)? Other than the price they look to be designed a little differently. Is one of the two better at preventing leaking? Thanks

Willys Jeep Parts Tech:
Alot of people prefer US made seals when available.

What is difference between 80093 and 800093k

Willys Jeep Parts Tech:
I dont see the one part number your referring to.

Does this seal fit correctly? 800093 is too tight on the crankshafts, a well documented issue it seems.

Willys Jeep Parts Tech:
Both our seals fit correctly. There are a few manufactures that they are tight. But we dont sell those.

Is there a simple picture showing the proper install

Willys Jeep Parts Tech:
Email mike@kaiserwillys.com and I can send you over an image.

Which way does the main seal go in. There is a flat side and one side with what may be referenced as a lip.
